Summary: Magnesium alloy has witnessed significant development in the field of biomaterials due to its excellent biocompatibility and biomechanics. However, its poor corrosion resistance in physiological environments poses challenges for clinical use. This study explores two main approaches to improve the corrosion resistance: alloying elements addition and surface coating modification. Surface coating modification is preferred as it avoids introducing new elements and offers simpler physical, chemical, or electrochemical improvements. The research summarizes and discusses the application and characteristics of six different surface coating modifications in the biomedical magnesium alloy field while highlighting the potential of combining modified coatings with various post-treatment technologies to enhance biocompatibility and achieve clinical functionalization.

Summary: Zirconium dioxide ceramic coatings were applied to the surface of 316L steel using the sol-gel method and then heated at 300 degrees C or 500 degrees C. The purpose of the coatings was to enhance the bioactivity and corrosion resistance of the steel in simulated body fluids. Analysis of the coated samples after 150 days showed increased presence of phosphates on the surface compared to uncoated steel samples. The deposition of ZrO2 coatings also improved the corrosion resistance of the steel in the simulated body fluid solution, as confirmed by electrochemical tests.

Summary: Magnesium is a promising candidate metal for biodegradable implants due to its biodegradation tendency and excellent biocompatibility. However, the high degradation rate and localized degradation in physiological conditions are major challenges for its successful implant applications. Recent research has focused on coating hydroxyapatite (HAp), a biocompatible ceramic material, on magnesium-based materials to improve degradation resistance and biocompatibility.

Summary: Monolayer Ta and multilayer Ta/Ti/Zr/Ta coatings were deposited on biomedical Ti6Al4V alloy by magnetron sputtering to enhance its performance. The effects of these coatings on microstructure, composition, mechanical and tribological properties, in vitro biocompatibility, and corrosion resistance were investigated. The results showed that the multilayer coating exhibited the highest hardness and the monolayer coating had the lowest friction coefficient. The wear resistance of the multilayer coating under low load was better than that under high load, and the Ta coating provided better biocompatibility and corrosion resistance than the uncoated alloy.

Summary: The study focused on the processing of titanium-based implants with improved corrosion resistance and Young's modulus close to that of cortical bone. Titanium matrix, hydroxyapatite, and hydroxyapatite-zirconia reinforced composites were successfully produced and tested for microstructure, mechanical, and corrosion properties. The Ti/(HA+ZrO2) composite scaffold showed higher corrosion resistance than the scaffold reinforced with only the HA phase, making it suitable for orthopedic and dental applications.

Summary: In recent years, metal biomaterials with excellent properties have been widely used in medicine. However, these coatings have limitations in meeting all medical needs. Schiff base, an important organic reagent, possesses various anti-tumor, antiviral, antifungal, and antibacterial activities. Schiff base coatings, by taking advantage of their properties, have great potential for improving the bioactivity of materials in medicine. This review highlights the preparation methods, properties, and advantages of Schiff base coatings, as well as their extensive applications in corrosion resistance, antibacterial, flame retardancy, and other fields. Suggestions for further research on Schiff base coatings for metal biomaterials are also proposed.

Summary: This study investigates the surface integrity measures in wire electric discharge machining (WEDM) of the Ni55.95Ti44.05 shape memory alloy (SMA) by varying spark parameters. Surface roughness and surface crack density have similar trends, increasing with higher spark energy density and decreasing with higher spark gap voltage and spark frequency. Foreign elements content and recast layer thickness decrease as spark energy density decreases, and spark gap voltage and spark frequency increase. SEM and optical profilometer observations reveal the presence of various surface defects, and EDS studies show the deposition of foreign elements on machined surfaces.

Summary: Comparisons were made between Poly Vinyl Chloride (PVC) foam based E-glass reinforced polyester sandwich composites and single and double layer E-glass reinforced PVC foam polyester composites in terms of their chemical, mechanical, thermal, and microstructural properties. Chemical analysis identified carbonyl groups and unsaturation sites. The double layer composite showed higher tensile strength and modulus, while the single layer composite had better flexural properties. Both composites showed similar thermal stability, but the double layer composite demonstrated better damping properties. The lightweight sandwich composites fabricated can be used in marine applications.
